Bakemonogatari Manga Set Vol 1-22 (Italian)

New from the comic shop and never read, photos are of a sample.
Plot: Koyomi Araragi is a third-year high school student who almost reverted to full human after briefly becoming a vampire. One day, her classmate Hitagi Senjōgahara, known for never talking to anyone, falls down the stairs and ends up in Koyomi's arms. He thus discovers that his partner's weight is almost zero, defying the laws of physics. After being threatened by her, who did not want her secret to be discovered, Koyomi offers her help, and introduces her to Meme Oshino, a middle-aged man who lives in an old abandoned school and who had previously helped Koyomi to become human again. Koyomi then finds himself involved in a series of "apparitions" that lead him to become interested in the cases of Mayoi Hachikuji, a little girl who has lost her way home; Suruga Kanbaru, a younger schoolmate, who is also a friend of Hitagi; Nadeko Sengoku, a friend of her sisters' age; and Tsubasa Hanekawa, a classmate of his.
